Behavioral Recognition Systems Inc. (BRS Labs) has extended the power of its AISight Cognitive Video Analytics software technology into use with pan/tilt/zoom cameras.

Previously, movement of PTZ cameras rendered the cognitive system ineffective. That’s meant that PTZ cams have typically needed humans watching them to accurately detect events. BRS officials say the new technology allows computers to watch the cams.

The new release of AISight takes visual input from the various positions of a PTZ camera, automatically learns and stores what activities and behaviors are normal for each view and generates real-time alerts that notify appropriate security personnel of abnormal behaviors—all without human involvement or training.

AISight learns and stores memories of normal behavior for each camera position when the view of the PTZ camera changes. When the camera moves from one position to another, AISight automatically calls up the memories associated with the new position and applies cognitive video analytics to detect abnormal behavior immediately.

A new Temporal Learning capability enables AISight to understand time of day and thus better understand environmental changes, such as how objects appear in varying lighting throughout the day. With this feature, AISight can also recognize scheduled events, such as a security guard passing through a secured area at a certain time of day, and issue alarms if someone else is in the area at a different time of day, for example.

The user interface now provides more detailed notifications and more complex distribution of alerts to security personnel, allowing AISight to fill the needs of small control centers monitoring 10 to 20 cameras, all the way up to large managed service providers and command centers monitoring thousands of cameras.

It offers a seven-tiered color-coded alerting system.

Users can integrate AISight’s Alert Management System with other Incident Management Systems (ISMs) through an open-standards API.

“AISight’s Cognitive Video Analytics technology is based on an ‘observe-learn-respond’ methodology,” said Ray Davis, CEO of BRS Labs. “Now, for the first time, analytics can be applied to PTZ cameras with our new release. The rules-based systems of yesterday are not able to address the complications associated with the constantly moving cameras called PTZs; consequently, these cameras have been relegated to simple sound and motion control. We recognized the expanded use of PTZs by the industry as a cost-saving trend and developed video analytics that work as effectively on these cameras as they do on fixed-position cameras.”

AISight is already being used at commercial sites worldwide. Within a week of the terrorist attacks in late November 2008, a major hotel in Mumbai, India, installed AISight and is now upgrading its installation to include PTZ cameras.

Other sites upgrading to this latest release include major banks in Brazil, power plants, and a nuclear site in the United States.

The standards-based AISight software seamlessly integrates with all fixed-position and PTZ cameras and is compatible with a wide range of third-party surveillance applications, data sources, and video-management software and devices. AISight supports the Real Time Streaming Protocol (RTSP) for video streaming and a plethora of application and device interfaces, including XML, SOAP, Web Services, JAVA, and Windows.

The technology has been deployed at various sites in beta-testing for about a year, the company said.

BRS Labs is demonstrating its behavioral recognition systems at ISC West Booth 20125, April 1-3.
